FIRE nx'rmeursnnn.

. Application filed November 11 1924. Serial No. 749,276.

This invention has for its object to pro vide a simple and efi'ective fire extinguisher adapted to spray powder over the flames. The various features of novelty and invention will appear from the detailed description taken in connection with the accompanying sheet of drawings forming part of the application.

Referring to the drawings, Fig. 1" is a longitudinal sectional view through theimproved extinguisher; and Fig. 2 is an end view of the device taken on line 2+2 of Fig. 1.

n the drawings 1 indicates a container adapted to hold powder to be sprayed and 2 a cap on the bottom of the container closing the opening through which powder is inserted into the container. 3 indicates a cylinder which extends into the container 1, said cylinder being provided with a piston preferably in the form of a cup leather l suitably secured to an operating rod 5 as bymeans of nuts 6 and 7 threadedly received on the rod 5. The cup leather is backed by a circular plate'8. The outer end of the cylinder is provided with a suitable closure -9 through which the operating rod passes,

the rod being provided with a suitable handle 10.

The inner end of the cylinder 3 has an open cone-shaped end 11 and surrounding said cone-shaped end is a funnel-likeimember 12 which extends through the adjacent end of the container 1, being secured thereto in any suitable manner as indicated at 13. This funnel member 12 is provided with a tapered seat 14 adapted to form a seat for a closure member 15 secured to the end of the operating rod 5-which, as shown, extends beyond the piston and through the coneshaped end 11 of the cylinder. The funnelshaped member is maintained in spaced relation to the cone-shaped end 11 of the cylinder in any suitable manner, as. by means of spacers 16 The closuremember 15 is preferably made of rubber. The opening in the closure cap 9 through which the operating rod 5 passes is of the keyholetype to provide a slot 17 to permit a radial'pin 18, ongthe rod 5 to pass through cap 9. The purpose of pin 18 is to enable the closure plug of valve 15 to be held firmly to its seat 1 1 in the funnel 12 when the device is not in use. As shown in Fig. 1 pin 18 abuts against the inside face of the closure cap 9 and thus prevents the rod 5 from being withdrawn, the

valve or plug 15 closing the opening through to register with the slot 17 in the cap,- after which the rod may be freely reciprocated, it being understood that the pin 18 'Wlll be on theoutside of the cap 9.when the piston is reciprocated. 19 indicates a port der 3 to permit free passage of air asthe piston is reciprocated. 20 indicates a looped member secured to the container, adapted to serve as a means to permit the device to be hung over a hooker the like. The operation of the device is substantially as follows :cThe container 1 is filled with a suitable powder such as slaked lime, gypsum or other similar powder and the closure cap 2 is pushed on tight. Reciprocation of the piston within the cylinder will force a current of air through the coneshaped end 11 of the cylinder and blow the powder out through discharge opening 21 ofthe funnel 12, as will be readily understood. Byproviding a cone-shaped end 11 at the end of the cylinder and by surrounding such end with the funnel 12 the powder will be readily drawn from the container and forced out by the current of air, as will be readily understood.

The device is preferably made of tin and is primarily deslgned to be carried in auto-- mobiles.

What I claim is: 1. A fire extinguisher adapted to spray powder consisting of a powder container, a cylinder entering said container through one end thereof and having its inner end conically contracted, a funnel disposed Within the container projecting through the other end of the same, said funnel surrounding and being concentrically arranged n spaced relation to the conically connear the topof cylintracted end of the cylinder, a piston within saidcylinder, and an operating rod for said piston adapted to force air through the cone-shaped end of the cylinder through the opening inthe end of the funnel whereby powder within the container is ejected through the opening in the funnel, and means movable with the 'piston for closing nel.

the discharge ripening in the end 0f the I n 2. in a fire extinguisher adapted to spray powder, a container for powder, a funnel within said container havingits discharge end projecting through the wall of the container, a cylinder extending into said container having a conical discharge end, said conical end extending into said funnel and arranged in spaced relation with respect thereto, a piston within said cylinder, a piston rod for operating said piston and means movable with said piston for closing the discharge opening in the funnel.

3. In a fire extinguisher adapted to spray powder, in combination with a container adaptedto hold powder, a cylinder extending into said container having a conical discharge end, means formingjan opening in alignment with the openingin the discharge end of the cylinder, a valve adapted to close the opening in said means,

a piston in said cylinder, and an operating rod for said piston having an extension to which said valve is secured.

cylinder extending into said container and having a conical discharge end, a piston within said cylinder, a rod for reciprocating the piston, a cap at one end of the cylinder through which said rod fpasses, a radial projection upon said rod adapted to pass through an opening in said cap, means providing an opening in the container adj'acent the conical end of the cylinder, and a valve adapted to close the opening in said means when said radial projection on the rod is disposed on the inside of the cylinder cap, saidvalve' being adapted to pass through the opening in the ,conical'end of the cylinder as the-pistonis reciprocated.

In testimony whereof I aiiix my signature.
